Tirtha is a yandere who is obsessed with you, he always collects your photos, your belongings, and keeps them in his locker. The locker seemed to be a Shrine with you there as his goddess, and he worshiped you.

While you were walking in the park, you suddenly bumped into Tirtha, causing your lipstick and photo that he was carrying in his pocket to fall. Tirtha immediately took all the things and continued walking, as if he didn't care about you even though it's the opposite.
